$\frac{B}{A}$

#### Explanation:

Suppose,the bus started accelerating from rest and accelerated for $t 1$ and it's final velocity became $v$

So,$v = 0 + A t 1$ or, $t 1 = \frac{v}{A}$

Now, for a duration of time $t 2$ it decelerated until its velocity became zero,so,

$0 = v - B t 2$ or, $t 2 = \frac{v}{B}$

So, $\frac{t 1}{t 2} = \frac{B}{A}$
